 note = {application/pdf, Effect of fatigue characteristics on burring of 0.2C-1.5Si-1.5Mn (mass%) ultra high strengthTRIP-aided sheet steel with bainitic ferrite matrix (TBF steel) was investigated for automotive applications. The combined rotational and downward force of the thermal drilling tool bit created friction heat. The height of the bushing was roughly 3 to 4 times the initial sheet thickness. The bushings are ideal for thread applications, as the strength of threads was significantly increased. We found that the fatigue life of TBF375 steel possessed the highest numbers of cycles to failure compared with TBF450 and TDP steels.},
